It's a tanish (maybe white) wire underneath the dist. It comes out of the harness where the oil pressure wire and vtec wiring is at.

It's a civic cx harness that was wired for vtec. Motor is a built B18C.

Never noticed it till recently.
My check engine light has been coming on for Overheating, but the temperature gauge isn't getting hot, the car isn't boiling, nothing. I am wondering if this wire has something to do with it.

 

In the last pic, you can see how it looks like a ground or something was sleeved around it at one time. :confused:

 

Not sure, but you best get rid of that universal ChinaZone rad hose.

 

It looks like an o2 sensor wire with that shielding like that.
